A Multi-Stage Partial Homomorphic Encryption Scheme for Secure Data Processing in Cloud Computing

Cloud computing has emerged as a prominent paradigm for the efficient storage and processing of large volumes of data. However, the security of sensitive information remains a primary concern for both users and service providers in cloud environments. Homomorphic encryption has proven to be a viable solution to secure data processing in cloud computing while maintaining the confidentiality of the data. In this research article, we propose a novel homomorphic encryption scheme based on multistage partial homomorphic encryption, specifically designed for secure and efficient computations in cloud computing environments. The proposed scheme combines the strengths of partial homomorphic encryption and multistage encryption techniques to enable secure and privacy-preserving data processing in the cloud.
